## What it is
go-extend is a Go utility library that collects commonly used helper functions to speed up development and reduce repetitive code. It provides performance-optimized alternatives to standard library functions like strings.Join, strings.Repeat, and strings.Replace, often using unsafe and in-place techniques to reduce memory allocations.

## Use cases
- join strings with fewer memory allocations in Go
- repeat or replace large strings efficiently
- convert string operations to []byte without type conversion overhead
- find optimized replacements for Go standard library string functions
- reduce boilerplate utility code in Go projects
- benchmark and compare performance of string manipulation functions

## When to choose
- your Go application is performance-sensitive and string/byte operations are a bottleneck
- you want drop-in, faster alternatives to strings.Join, strings.Repeat, or strings.Replace
- you need a curated set of common utility functions to cut down repetitive code

## When to avoid
- you prefer to avoid unsafe-based code paths in safety-critical or audited codebases
- your project only needs one or two small helpers and you'd rather write them yourself
- you need actively maintained libraries with frequent updates and broad community support

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools, concurrency, error-handling, benchmarking
- domain: developer-tools, performance
- platform: go, cross-platform
- tags: go-stdlib-extensions, string-manipulation, byte-slice, performance-optimization, unsafe, utility-functions, exstrings, exbytes, algorithms
